7. ASSEMBLY AND START-UP
Before installing the extension arm in the facility, you should:
1) Examine the load-carrying capacity of the constructional elements of the building, where the RO extension
arm shall be installed,
2) Prepare the necessary constructional elements connected with the building structure within the screw
connection points of the mounting plate (of the wall bracket).
The diameter, hole pattern and quantity of holes for the bolts, as well as the diameters of mounting bolts of the
mounting plate of RO extension arms, are given in the attached drawing.
When assembling, pay attention to the vertical position of the mounting plate. In case they deviate from verticality–
the arm will tend to set always into the same position.
The swivel construction provides:
• installing the extraction fan,
• connection to the ventilation discharge ducting.
Extension arms type RO-E-L/X
RO-E-L/X extension arms are designed for attachment of the ERGO-L extraction arm at its free end. The extension
arm should be installed to the wall using a WB-RO/L wall bracket (in case of extension arms RO-1,5-E-L/X and
RO-2,5-E-L/X) or directly to the wall (RO-4-E-L/X).
CAUTION: The wall bracket is not standard equipment for the arm, so it should be ordered separately.
